Darkbit

MITRE ATT&CK does not currently catalogue Darkbit, so this is our assessment of the techniques it uses, drawn from public reporting. The techniques themselves, and every "what that means" definition below, come from MITRE ATT&CK v19.2. Confidence: medium. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: darkbit executes malicious payloads via PowerShell scripts to stage ransomware deployment.

   What that means: Adversaries may abuse PowerShell commands and scripts for execution.

2. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: darkbit persists via Registry Run Keys to ensure recurring execution after reboots.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: darkbit disables antivirus tools and security monitoring utilities to evade detection.

   What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.

4. T1027.016 Junk Code Insertion Stealth

   What they do: darkbit inserts junk code into legitimate binaries to evade static analysis.

   What that means: Adversaries may use junk code / dead code to obfuscate a malware’s functionality.

5. T1070.004 File Deletion Stealth

   What they do: darkbit deletes Volume Shadow Copies and backup directories to prevent recovery.

   What that means: Adversaries may delete files left behind by the actions of their intrusion activity.

6. T1135 Network Share Discovery Discovery

   What they do: darkbit scans network shares to identify victim file structures for encryption targets.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

7. T1021.002 SMB/Windows Admin Shares Lateral Movement

   What they do: darkbit moves laterally through SMB/Windows Admin Shares to encrypt additional systems.

   What that means: Adversaries may use Valid Accounts to interact with a remote network share using Server Message Block (SMB).

8. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: darkbit exfiltrates sensitive data via encrypted channels before deploying ransomware.

   What that means: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.

9. T1486 Data Encrypted for Impact Impact

   What they do: darkbit encrypts victim files using strong symmetric encryption before demanding ransom.

   What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.

10. T1490 Inhibit System Recovery Impact

    What they do: darkbit runs commands to inhibit system recovery processes like restore points and backups.

    What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.

Software Darkbit has been seen using, grouped by what it is used for. Legitimate administration tools appear here because these actors routinely abuse them — presence in this list is not itself malicious.

Dear Colleagues,
We’re sorry to inform you that we’ve had to hack [snip] network completely and transfer “all” data to our secure servers.
So, keep calm, take a breath and think about an apartheid regime that causes troubles here and there.
They should pay for their lies and crimes, their names and shames. They should pay for occupation, war crimes against humanity,
killing the people (not only Palestinians’ bodies, but also Israelis’ souls) and destroying the future and all dreams we had.
They should pay for firing high-skilled experts.

Anyway, there is nothing for you (as an individual) to be worried.
That’s the task of the administration to follow up our instruction for recovering the network.
But, you can contact us via TOX messenger if you want to recover your files personally. (TOX ID: AB33BC51AFAC64D98226826E70B483593C81CB22E6A3B504F7A75348C38C862F00042F5245AC)

Our instruction for the administration:
All your files are encrypted using AES-256 military grade algorithm. So,
	1. Don't try to recover data, because the encrypted files are unrecoverable unless you have the key.
	Any try for recovering data without the key (using third-party applications/companies) causes PERMANENT damage. Take it serious.
	2. You have to trust us. This is our business (after firing from high-tech companies) and the reputation is all we have.
	3. All you need to do is following up the payment procedure and then you will receive decrypting key using for returning all of your files and VMs.
	4. Payment method:
		Enter the link below
			http://iw6v2p3cruy7tqfup3yl4dgt4pfibfa3ai4zgnu5df2q3hus3lm7c7ad.onion/support
		Enter the ID below and pay the bill (80 BTC)
			[snip]
You will receive decrypting key after the payment.

Notice that you just have 48 hours. After the deadline, a 30% penalty will be added to the price.
We put data for sale after 5 days.
Take it serious and don’t listen to probable advices of a stupid government.

Good Luck!
“DarkBit”
